MACHINE FOR SPINNING PAPER.

Specification 0: Letters Patent.

Patented Dec. 5, 1916.

To all whom it m (q concern:

Be it known that we, Enwann Scinnn'r, a subject of the Emperor of Austria -Hungary, IVaL'rnn Srnrrnxs, a subject of the Emperor of Germany, and F RANK F. REINKE, a citizen of the United States. all residing at (.leveland, in the county of (uyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Spinning Paper, of which the following is a specification.

This invention pertains to an improvement in a machine for spinning paper, and the improvement consists more particularly in the novel and useful mechanism for maintaining a flat strip ofpaper under tension during spinning operations, all substantially as herein shown and described and more particularly pointed out in the claims. In machines of this character. the paper strip is moistened to facilitate spinning operations, and the object of this improvement is to produce uniform saturation and sufficient tension continuously without tearing or severing the paper strip under the pulling and twisting strains of spinning operations.

In the accompanying drawings, Figure 1 is an end elevation of a sectional portion of a spinning machine containing the present invention; Fig. 2 is a front elevation of the machine: Fig. 3 is a transverse section, enlarged, of the front upper portion of the machine, and Fig. 4 is an enlarged end elevation of the same portion of the machine looking in from the right, showing the operating gears for the several tension and moistening rolls or rollers for the paper strip. Fig. 5 isa plan view of the mechanism shown in Fig. 3, and Figs. 6 and? are end and front views, respectively, of the same parts.

The machine as thus shown comprises a main supporting frame F, a series of spinning spindles S vertically disposed at the front of said frame and driven by power connections of any approved kind, belts g seen in Fig. 1 being used in this instance to convey the power. Now describing the mechanism cooperating with one of the spinning spindles, the paper strip 2 is brought to the machine in a roll R mounted on a suitable spool which is removably supported on a short stud shaft 3 at one side of a standard. f fixed upon the main frame F, and feeding of the paper strip is directly downward from the front side of the roll R to a gravity device or weight w adapted to rest upon the fiat paper strip and supported by a table or platform 4 on the top of the machine and beneath which weight the dry paper strand or strip is drawn under the de sired tension. Thence the paper passes upward and forward over a shaft 6 between spaced collars (3' and thence forward over a relatively wide idler roll 7 and downward to the tension and dampening rolls 8 and 9, respectively. The strip 2 passes down behind roll 8 and forward and between both rolls and thence downward on a substantially straight line to the spinning spindles S which rotate rapidly to twist or spin the strip and also to wind it upon the spinning spool. Manifestly, the strip is under a certain degree of tension from the spinning spool upward but to avoid breakage of the strip which is wet, the feeding of the strip is materially assisted by rollsS and 9 before the paper is weakened to any great degree by absorbing the water which is carried to the strip by roll 9. Moisture in the desired quantity is carried forward from the reservoir 10 by the successive rollers 11 and 12 to the roller 9, the roller 11 dipping into said reservoir and the roller 12 being in contact therewith and with roller 9. The said rollers 9 and 12 are supported on suitable shafts mounted in hearings in pivoted and adjustable arms 13 and 14, respectively, on the main frame, and adjusting screws 15 and 16 serve to control the contact of said rollers through said arms and thus regulate the quantity of moisture carried forward by said rollers. The lower screw 16 is carried by a support 17 rigid with the top of the hearing for shaft 30, while screw 15 is carried by arm 14. Roll 8 is relatively larger than roll 9 and is held in working relation therewith by gravity, the primary support for ro1l 8 being by arms 18 fixed to and projecting forwardly and downwardly from table 4 and the secondary support being by adjustable slides 19 having channels 20 in which the ends of the roller shaft 21 of roll 9 have rotatable and sliding engagement.

The paper strip 2 is comparatively narrow, depending on the size of thread wanted, the Width being, say three sixteenths of an inch, more or less. Consequently, said strip is easily broken especially when damp or wet. Butwith the tensioning and dampening mechanism described the strip is stretched and carried forward to the spindle rapidly and without break, notwithstanding the variable pulls and twisting strains imposed upon the strip. The friction or tension member to is of comparatively light weight, usually weighing less than a pound and in actual size about an inch across, and say, two and a half inches long, and its. main function is to steady the feed of the strip from roll R and prevent slack. Said member w has guide pins 22 in its bottomv engaged in holes in the platform 4 and can be bodily removed by hand to introduce the strip beneath.

Each paper roll R consists simply of a paper strip of narrow width wound about itself with. accuracy, so that the rolls are .as

narrow as the width of the strip itself and its actual diameter before unwinding is ap proximately twenty inches. The post or standard which carries the roll serves as a guardon one side. to keep the paper from collapsing or working off on that side, while a blade 23 is fixed on the spool of said roll to confine the paper roll on the other side. The work of removing and replacing the rolls R is facilitated by providing a stand- .ard or support 7 with a stud shaft located above the tensioning and dampening mechanism, and the feed of the paper strip is also in plain view from the roll to said mechanism. It will be seen in Fig. 2 that there is a similar roll equipment for each of the several spindles S, five sets of tensioning and dampening rolls being shown in this instance and which represents one subdivision, say of ten, in the same machine, and each and all the working units in a given section have corresponding aper rolls R and supporting means there or.

The spindles of the tension rolls 8 being engaged in open slots in the slide of bearing 19, the said roll has a free up and down play therein to obtain a uniform and sustained travel or supply of the strip to the' spinning spindle with a minimum power. Heretofore, in this type of machine the practice has been to provide a constantly sustained feed of the strip by a set of positively-acting feed rolls rotating at' a fixed speed, thereby producing a continuous feed of a given length of paper in a given tlme regardless of the speed of the spindles or other parts. It follows that there was a tendency to either overfeed, or underfeed the paper and there was no harmonious cooperation between the parts. Hence, there was also constant tendency to wavering'in the supply of the strip and frequent breakage and imperfect spinning results. These troubles are very serious and materially diminish the amount of work done and necessitate much expensive supervision, but in the present invention these troubles are mainly eliminated as the strip is drawn and fed and also be noticed that by the present construction the feeding andtravel of each strip is individually controlled from its roll 8 through to the spinning spindles and it works out that each individual spindle practically controls the supply of paper thereto and the paper will not travel faster than it is taken care of by the spindle. .Uniform dampening of the paper strip while under motion is also essential to successful continuous operationof the, machine, and to that end, the paper strip 2 is shifted longitudinallyof the .rolls by a reciprocable movement of shaft 6 during feeding operation of the strip. The contactingarea of roll 8 is thereby not confined to a single narrow circumferential face; the width of said strip and-the dampening area of roll 9 are also not limited to the same narrow circumferential path, but on the contrary, new and changing contact surfaces are under action to maintain the proper feed and" especially the proper distribution of water to the strip.

The means for imparting reciprocable movements to shaft 6 comprise a crank or shown in this instance as a means to that end, see Fig. 2. Rolls 9 and 12 are driven by a train of gears 32, 33 and 34, respectively, located at the 'right of the machine,

see Figs. 2, and 4, gear 32 being aflixed to shaft 30 of roll 11.

The platform 4 is supported by rack bars '35 and carries the arms 18 in which the rolls 8 are loosely and removably mounted, as hereinbefore described Said rack bars are slidably mounted on the main frame and the gear teeth 36 on said bars are engaged by toothed segments 37 fixed on an oscillatory shaft 38,'whereby the latform 4 and parts carried thereby are a apted to be moved forward or back relatively to thedampening roll -9 and the paper roll R. The shaft 38 is actuated by hand lever 38 or equivalent means.

'As shown in Fig. 3 the parts are adjusted to approximately but not quite the maximum rearward-position and as shown'the roll 8 rests upon the roller 9 in vertical axial alinement therewith and the roll 8 is free to move forward and upward under any lifting strain imposed by the paper strip 2. A fifty spindle machine of five sections each requires the service of one or two attendants, and the removal of the spools on of exposure of the strip to the moisture on roller 9 will be correspondingly reduced. This supplements the adjustments by the screws 15'a-nd 16 to regulate the amount of moisture to be applied to the paper strip.

\Vhat We claim is:

1. A machine for spinning paper strips having a main frame and a platform slidably mounted on the main frame, and slack take-up means for the strip mounted thereon comprising aloosegweight to bear on the strip and an idler over which the strip is adapted to pass from said weight, in combination with a dampening roller and a roll loosely supported in gravity-seating relations therewith for tensioning and dampening. the paper strip carried forward from said idler.
